The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。

There are two causes leading fractures of the endodontic instruments. Firstly as the value of the toque inc1ases beyond the limited toque, the instrument will twist with no increase in toque and will fracture soon. The value of limited toque is proportional to 3 squares of the file radius.

根管器械断裂的原因主要有2个：一是扭转超过极限扭距，器械顺着扭转的方向发生塑性扭转直至断裂，圆杆的极限扭距与其半径的3次方成正比；二是器械在循环载荷下发生疲劳损伤，最后突然断裂。

Around 8pm the light was starting to fade. We were one pitch below Camp 5. Interestingly enough we heard lots of voices above us. I avoided having to lead the last pitch by getting the French party to throw down a rope that we could jumar up. Like the first night we were surprised how many folks were up and around this bivy. There was the French party. There was the Nose-in-2-days party and there was a Nose-in-hopefully-5-days party. There five of them in the last party and they had 3 or 4 huge haul sacks. There was one guy who must have been 275 pounds. He was the designated haul bag mule.

大概晚上八点，光线暗了下来，我们在第五营下一个绳距，有趣的是我们听到上面有很多声音，我不用先锋最后这个绳距，因为法国队抛下一条绳子，我们只要用犹玛上升即可，就像第一个晚上惊讶，好多人上到这个过夜处，有法国队，还有一个两天爬完Nose的队伍，还有一个希望在五天内能爬完Nose的队伍，最后这一队有五个人，三四个拖包，其中有个家伙大概有275磅重，他大概是专门拉拖包的吧。

"Archaeological studies suggest that ancient remains found in Belgium, Germany and Western Russia, which date to 13,000-31,000 years ago, were most similar in body size to the Great Dane, while those from the Middle East dating to about 12,000 years ago were most similar to a small terrier," lead author Melissa Gray told Discovery News.

本文主笔米莉莎·戈瑞在发现频道新闻中说：&考古研究发现，在比利时，德国及西俄发现的古代狗化石(距今约13，000—31，000年)其原形或与大丹犬体积相近。而中东发现的(距今约12，000年)则与小泰勒犬相近。&戈瑞来自威斯康星大学遗传学研究室。

The reference distance is 25 cm.All magnifications are calculated from this distance (magnifiers, magnifying glasses, telescopes).

标距的规定是25厘米，放大镜、放大器和望远镜等光学产品的放大倍数都是以这个标距来计算的。

It is concluded that the match of K1 qn 1 source rock and its internal overpressure controls the range of oil accumulation and distribution, the vertical match of overpressure and T2 source fault controls the depth and layer of oil accumulation,the plane match of overpressure and T2 source fault controls the site of oil accumulation in Fuyang oil layer.

具体表现为：①青一段源岩生成油&倒灌&运移区内T2源断裂发育的区块使扶杨油层油富集；②青一段源岩生成油&倒灌&运移区内，距T2源断裂越近，断距越小，越有利于扶杨油层油富集；③青一段源岩生成油&倒灌&运移区内，油主要富集在T2源断裂的下盘。

The autoaligment instrument and accuracy turntable with digital display are used to detect the step angle after 32 subdivision, and the experiment results are given, the mean-square error of step angle after 32 subdivision is less than 3.7%.

为了检测32细分后的步距角，采用了自准直仪加精密数显转台的光学测量方法，并给出了实验结果，32细分步距角的均方误差不大于3.7％。

Having started the short right hook, Bradley dropped it in mid-swing to try a roundhouse — too late.

打出短距右勾拳后，布莱德利打出一记中距摆拳，尝试大迂回——但太晚了。

The results indicated that the axial velocity distribution of the mixture was a parabola-like curve along the radius and the change of the velocity was larger in the region within 0%～25% of the pipe width (about 15 mm) from the pipe walls, but smaller in other positions. The vortex changed greatly in the region within 0%～16.7% of the pipe width (about 10 mm) from the pipe walls and then decreased gradually to zero at the pipe center.

结果表明，混合颗粒的轴向速度呈类似抛物线状分布，在靠近管壁约0%～25%管宽范围内，即在试验装置距管壁约15 mm范围内，轴向速度变化较大，其他位置处变化较小；涡量在靠近管壁约0%～16.7%管宽范围内，即在试验装置距管壁约10 mm范围之内变化明显，从距离管壁10 mm到竖直管中心涡量逐渐减小到接近为零。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
